UNITED' STATES PATENT OFFICE ALEXIS F. GILLET, OF OMAHA, NEBRASKA,ASSIGNOR TO J'UBILE MANUFACTURING i COMPANY', OE OMAHA, NEBRASKA, ACORPORATION or NEBRASKA srnri SEGMENTAL WASHER Application led August 2,1929. Serial No. 383,135.

Therpresent invention relates to improveV ments in split segmentalwashers yand methods for producing the saine, and has for an object toprovide an improved segmental washer, the parts or sections whereof areadapted to member together in an improved manner whereby the saine arereadily atl tached and detached.

Another object of the invention is to provide an improved splitsegmental washer whereby the same may be so positioned upon a shaft thatit will-function as a shim to enable the pinions and gearing to memberto.- gether in an improved manner whereby the teeth of the pinion willinterfit and mesh without friction. Y

A further object and advantage of the invention is that by formingapertures through the plates the said apertures will serve to retain theoil when the device is in use upon machinery, suoli as a line shaft. `Inother words, the apertures of the device will contain oil or grease.

A further obj ect of the invention is to provide an improved shim whichis applicable to the shaft of the gearing whereby said parts may beshimmed together for substantially perfect register with adjacentgearing.

A still further Object of the invention is to provide an improved splitsegmental washer or shim which is of simple and inexpensive constructionand in which the sections Or parts of the shim may be fitted toshim orwasher may be united in a novel andV simple manner.

A still further object of the invention is to provide an improved methodfor making washers or shim by the use of a punch-press in which a tangis punched from one of the plates forming a tang through the4remainplate .to unite the same together in grouped relation and wherebythe tang may be clinched orI upset to avoid anylikelihood of theseparation of the parts.

lVith the foregoing and other objects in view, the invention will bemore fully de- Y scribed hereinafter and more particularly pointed outin the appended claims.

Figure l is an edge view of the section shown in Figure 3 and taken fromthe right side of Figure 3. Y

Figure 5 is a side view showing the completed shim or washer with thetwo sections shown inFigures l `and 3 united.

Figure 6 is a cross section taken Von the line (3*6 in Figure l.

Figure y7 is -a side view showing a slight modification.

Figure 8 is a cross sectional view taken along the line 8-'-8 in Figure7 and Figure 9 is a similar view taken along the line 9-9 also in Figure7.

Referring more particularly to the draw ings, it will be understood thatthe two half or segmental sections of the improved washler aresubstantially identical andtherefore but one will be described. Eachsection consists of an intermediate plate 2O and two side plates 22 and22. These plates arerelatively offset, or rather the intermediate plateie offset longitudinally ory circumferentially from the twoiside'plates22 and 22 whereby one end 21 ofthe intermediate plate 20 projects beyondthe adjacent ond of the side plates 22 and 22 and thus. forms a.projecting tongue, which is perforated as indicated at 24. The adjacentend 30 of the two side plates 22 and 22 form shoulders to take soVprovided with a perforated tongue 21 at one' end and with a recesscomprised between the walls 23 at the opposite end. The tongue 21 of onesection will come opposite the recess upon theother section so that thetongues and recesses of the two' sections will interfit. Bosses 25 arepunched from the walls 23 into the recesses as indicated in Figure 2 andthese punched in bosses are adapted to register with the perforations 2lof the tongues 21. 1t will be understood that the washer Vplates i arepreferably made from metal or some other material possessing inherentresiliencyT so that thebosses may snap or clip into these recesses 24 inthe act of inserting the tongueV 21 between the walls 28 of therecesses. rlhis will form a convenient means for attaching the twosections of the washer and kfor detaching the same. It only-becomesnecessary to exert a slight force in moving the tongue into and out ofthe recesses. Once in the recesses, however, the tongues will be firmlygrippedin place and the washer or shim will remain placed until forciblyremoved.

As shown in Figure 6, the side and intermediate plate may be joinedtogether by punching a tang 26 from one of the side plates 22 throughthe intermediate plate 2O and the associated side plate 22. For thispurposeit is convenient to initially form registering perforations 27 inthe intermediate plate 2O and the side plate 22. In Figure 6 the tang 26is shown as projecting beyond the side plate 22 to form a burr whichassists in holding the plates together. If desired this burr may beremoved. The tang 26 may be formed by means of the downward movement ofa punch-press. The punch press will preferably operate upon the blankwall of the side plate 22, which blank wall furnishes the material outof whichthe tang 26 is formed in the operation of punching. It will beunderstood that this method of punching is more economical than the oldway of attaching the plates by the use of rivets. As before stated, theburr formed `may be ground off or otherwise removed.

This punching operation may be performed at several places along theplates. In Figure 1 three such tangs are shown. All

these tangs are punched from the one side plate 22. In case it is notdesirable to have the operation attended by the formation of a burr, theconstruction shown in Figures 7 8 and 9 may be resortedk to. In thesegures the three plates are assembled in substantially the same mannerand the operation of punch-pressing is also performed in order to securethe parts together, but the modification consists in performing theoperation from opposite sides of the segmental section. As shown inFigure 8 a burr 26 is punched from the side plate 22 through alnarrowperforation 33 in the intermediate plate 2O and into av widerperforation 34 in the companion side plate 22.V The burr, shown at 28 isodset upon the face of the intermediate plate 2O and this burr Vlieswholly within the plane of the opposite side plate 22.

As shown in Figure 9, two adjacent tangs appear in relatively oppositedirections, one tang 26 from the plate 22 and the adjacent tang from theopposite side plate 22. The tangs simply pass through the smalleropenings in the intermediate plate 20-and are offset within the largeropening of the opposite side plate. Y

By this means two of the-plates are joined by each of the burrs and theco-operating burrs and tangs act to join the three plates together intoa unitary structure. In this manner the side surfaces of the device areleft smooth and therefore any grinding operation is dispensed with.

In the use of the device, the washer sections thus formed are simplybrought together in opposite directions upon the shaft and the tongues21 are forced between the walls 23 of the recesses, the rounded internalportions of the bosses 25 snapping into the recesses or perforations 24inthe tongue 21 and thus holding the two or more sections of the washerin place as shown in Figure 5 and about the shaft. In removing thewasher, one or more of the sections is gripped and forced in an oppositedirection from the companion section whereby to withdraw the tongue fromthe recess and from the binding action of the bosses 25. a t will beappreciated that the improved steps of the method for assembling anduniting the plates together will bind the same into a strong unit by asimple and economical process without the use of rivets. It will befurther appreciated that in View of the fact that no rivets are employedto hold the tongue 21 in the recess, that a diflicult operation isdispensed with and the diiiculty of removing the shim is also avoided.

The tangs and bosses may be formed, if desired, opposite to the showingin Figure 1 of the drawing, namely, apertures may be formed in thegrooved portion of the device and a boss formed upon the tongue portion'thereof.

Referring to Figures 7, 8 and 9. The parts marked on the drawing 22 and22 are identidies, and the same stroke ofthe dielperforates cal and areformed with the same b'lanking the apertures for later receiving a bosson the tongue portion. By later is meant when the device is assembled inuse on a lineshaft.

The medial plate 2O is formed separately with a separate and differentblanking die.

The steps of the method in forming the device are as follows:

In assembling the pieces, the piece marked 22 is placed over a piecemarked 2O in the drawing. Or, of course, plate 22 may be placed over thepiece 20. The said parts are now attached together by means of forming aburr 28 on the tang 26.

It will be understood that the tang 26 is formed during the blankingprocess. Name ly, a die comes down and cuts the piece out and at thesame time forms the tang. The burr to hold the parts together is formedduring the assembling thereof. v

Next the piece marked in the drawings 21 is placed over the two piecesjust now described as assembled and the burr is formed through theapertures in a manner whereby the burrs are all inside of the interiorsurface of the device.

I desire it to be understood that Various changes and modifications maybe made in the size, form and proportions of the various parts and thesteps and processes of the method may be varied widely, provided allsuch modifications in the construction and the method fall within thescope of the following claims.

I claim:

l. A split segmental washer composed of sections comprising side andintermediate -plates having means to attach companion sections together,and tangs punched in opposite directions from the side plates throughthe intermediate plate and upset upon the intermediate plate.

2. A split segmental washer composed of sections comprising side andintermediate plates, said side plates having staggered perforations,said intermediate plate having smaller perforations registering with thefirst named perforations, and tangs punched in opposite directions fromthe side plates through the registering perforation and upset againstthe intermediate plate within the perforations of the side plates.

In testimony whereof, I have affixed my signature.
